In 'Thor,' that was my own hair. I grew it out. But I have naturally curly, blonde hair, so I'll never look like that. By the time I got to 'The Avengers,' I had come off two other films, which required me to have it very short. So I dyed it again and it was long enough to use a part of my hairline.

With any role, you're extending yourself and acting out things that never happened to you.

Everythings a choice. Nobody's born good. Nobody's born evil. It's always a choice.

The weird thing about serious acting is I've always done impressions of people, all my life, and I did the thing called a balloon debate. The idea is there's a hot air balloon traveling across the Atlantic and it's going down and you have to give a speech as to why you should stay in the balloon. Six people are going to be chucked out and you want to stay.

Life is generally pretty damn amazing if you let it be.

The best revenge against bullies is absolutely, resolutely, never to let them change who you are. Know that whatever bullies say or do - it comes from their weakness, not yours.
